Numens - Model 403-001 -conventional smoke and heat detector

403non-addressable photoelectricsmoke/heat detectors are state-of-the-art detectors suitable for connection to 2-wire or 4-wire non-addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors . Advanced electronics in conjunction with a photoelectric smoke sensing chamber and an electronic thermistor provide early detection of fire and high immunity against unwanted alarms. The heat sensor provides sensitive rate-of-rise operation or fixed-temperature operation when the response threshold value is exceeded. The 403non-addressable detector range provides fire detection and alarm system designers with an economicalsmoke/heat detector for life safety and property protection applications
